heading represents a single
concept, whereas a multiple-word
heading may represent a single
concept or multiple concepts.

Pre- coordinated multiple-
concept headings: A

main types of subdivisions:
topical, form,
chronological, and
geographical subdivisions

combinations of main-heading/
topical subdivisions:
